Well I don’t know if you all had the same problem as me but I’ve solved mine! I spent 30 min trying to connect the antenna clip to the wrong place! Right next to the Antenna clip socket is the screw hole for the covering plate. I thought it looked a bad design but lined it up with tweezers as above to no avail. Later after giving up I spotted the same screw holes for the upper cover plate for LCD etc and realised my mistake. The antenna clip socket is to the right of the screw socket and tiny and easy to miss. The antenna cable runs in a diagonal groove in the loudspeaker casing towards it. Once I lined these up it popped straight on in literally 2 seconds.
I wonder if some of you guys have the same issue?
All the best
